' Application filed April 16, 1913. Serial No. 761,583.

To all whom it may concern Be it known that we, CHARLES F. Conn and QUINCY CARR, citizens of the United States, residing at Huntington, in the county of Cabell and State of West Virginia, have invented'certain new and useful Improvements in Gas-Burners, of which the following is a specification, reference being had. to the accompanying drawings.

This invention relates to improvements in gas burners and more particularly to a burner which is especially designed for use in connection with portable gas stoves, the invention having for its primary object the provision of means whereby the heating capacity of the stove may be regulated.

Another object of the invention is to provide a burner for the above purpose having independent fines or passages, each provided with spaced jet tips, and a regulating valve to independently control the supply of gas to said passages.

Another object of the invention is to provide an improved construction of the burner body made up of a plurality of sections which may be .readily disassembled when necessary in order to clean the burner tips.

A still further object of the invention resides in the provision of a burner head of improved construction and means for easily and quickly attaching the body of the burner- ,thereto or detaching the same from said head.

A still further object of the invention is to generally improve the construction of burners of the above character whereby the efiiciency, convenience and serviceability of portable heaters are materially enhanced.

With the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that we shall hereinafter fully describe and claim.

; For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which- Figure 1 is a front elevation partly in section showingour improved burner mounted within a portable heating stove. Fig. 2 is an enlarged horizontal section taken on the line 22 of Fig. 1; Fig. 3 is a section taken on the line 33 of Fig. 1; Fig. 1 is a section taken on the line l4 of Fig. 2; and Fig. 5

is a detail fragmentary perspective view of the sections of the burner body disassembled.

Referring in detail to the drawings, 5 designates the body of a portable heating stove which may be of anyqordinary or approved construction, the same including the usual copper reflector plate 6.

The numeral 7 indicates generally our improved burner which is horizontally arranged within the stove contiguous to the rear wall thereof and at the upper end of the reflector plate 6. The body of this burner is made up of a plurality of sections which are illustrated in detail in Fig. 5. The body member 8 is of channel form incross section and constitutes the front wall 9 and the top and bottom walls 10 and 11, respectively of the burner body. The front wall 9 has formed therein at spaced points, a plurality of tips or nipples 12. These tips may be conveniently formed upon the wall 9 by punching said wall outwardly and providing the same with lava jet tips. A second longitudinally extending channel shaped member 13 is arranged within the body member 8 of the burner. This member has its body wall 14 located intermediate the front 9 of the burner and the rear or back wall 15 thereof. This back Wall is constructed of sheet metal and has its longitudinal edges grooved or channeled as indicated at 16 to receive the edges of the upper and lower walls of the members 8 and 18. The walls of the longitudinal channels 16 are then compressed or crimped to retain the sections of the burner body in assembled relation. The front wall 9 of the burner section 8 is also provided with openings 17 said openings being alternatelyarranged with respect to the burner tips 12. It will, however, be understood that if desired, two or more burner tips may be arranged in the front wall between adjacent openings. Through these openings 17, the burner tips 18 which are integrally formed with the wall 14;.of the member 13 extend, said latter tips projecting from the face of the wall 9 for substantially the same extent as the tips 12. I

The front wall 9 of the burner section 8 at one of its ends has integrally formed the fines or passages 21 and 22 respectively which are produced by the sectional construction of the burner body. The longitudinal edges of this tongue are adapted to be bent inwardly upon the upper and lower walls 10 and 11 of the burner section 8 and over the edges of the tongue 19 as shown at 23. The end of this tongue 19 is bent over the contiguous edge of the tongue 20. It will thus be seen that a secure and effective closure for one end of the burner body is obtained with out necessitating the use of additional elements, thus avoiding the use of screws or analogous fastening elements which are liable to become loosened. The tongues 19 and 20 are provided with openings in registering relation to receive a suitable fastening screw or bolt 2a whereby theend of the burner may b esecurely attached to one of the side walls of theheater 5.

The burnerhead indicated at 25 is constructed of cast brass. This burner head is located exteriorly of the heater'and is provided upon its upper end with a laterally disposed tubular extension 26 of. rectangular form in cross section to receive one end of the burner body. Screws 27 secure the head and body of the burner together. The burner head 25is further provided with an interior centrally located longitudinally extending partition wall 28 which terminates suhstantially midway between the upper and lower ends of said burner head. The upper end of this partition wall does not extend into the laterally disposed portion 26 of the burner head and, when the burner body is assembled uponsaid head, is disposed in alinement with the wall 1 1 of the burner section 13. The ordinary gas supply valves 30 are arranged in the burner head 25 and control the supply of gas to the spaced flues 31 and 32 respectively which are formed by the partition wall 28. These flues communicate with the fines or passages 21 and 22 respectively of the burner body. The lower end of the burner head 25 is provided in its bottom and side walls with openings 33 to either of which the gas supply pipe is adaptrods or stems 37.

ed to'be connected, the other opening being plugged. v

Within the laterally extended upper end 26 of the burner head, and against the edge of the partition wall 28, the plate 34: is arranged and secured in any preferred man-. ner, This plate is provided wit-h spaced openings 35, which afford communication between the fiues 21,31 and 22, 32 respectively. Around these openings, valve seats are formed to receive the valves 36 provided upon theinner ends of the supply regulating These valve stems have threaded engagement in one wall of the stuffing boxes 25?. It will be readily understood that by simply adjusting these valve stems, a greater or less amount of gas will be perreduced.

mitted to flow from the lines 31 and 32 into the fiues or passages 21 and22 of the burner From the foregoing, the construction and operation of our'improv'ed burner will be readily understood. In the burner of this character now in general use, the gas pressure is reduced at the supply valve so that an imperfect combustion and flame results. With our improved burner construction, when it is desired to reduce the ordinary heating capacity of the stove, one of the v valves 37 is adjusted to close communication between one of the. passages in the burner body and one of the fines in the head 25, thus shutting off the supply-of gas to one series of tips 12 or 18 as the case may be. Thus it is unnecessary toadjust the supply valves in any manner,'and the pres sure of gas to the other series of tips is not The pressure in each of the fines may also be independently adjusted by means of the valves 36, irrespective of whether or not the full pressure or only a part thereof is admitted from the supply pipeinto the burner head. Thus a constant flame from the two series of jets of the same or 'difierent sizes may be maintained. It will thus be apparent that by the use of our improved burner material economy in the use of the stove is effected. It is a well known fact that in portable heating stoves of the character above described, when the gas jets are lighted, the person applying the match or lighted taper thereto is subjected to considerable danger in view of the fact that when the full supply is turned on, the upper portion of the heater body' fills with gas, and this accumulated gas when ignited flames outwardly through the opening. in the front wall of the stove so that there is great liability of the garments or hair being burned when stooping in front of the stove to apply the match. By means of our invention, this probability is entirely, obvi-' ated, as the gas may be first admitted to the passage 21 or 22 and after it is ignited, the

additional supply then admitted to the other passage. Owing to the sectional sheet metal construction of the burner body, itwill be appreciated that the same can be produced at very small manufacturing cost and the parts thereof easily and quickly assembled.

When it is necessary to clean the fines or burner tips, these sections may be disassembled for this purpose, while the entire burner body can be easily removed from the burner head for the purpose of cleaning the latter. v I

It is to be understood that while we have particularly described "and illustrated the present preferred embodiment of our inthereof Without departing from the essential features or sacrificing any of the ad vantages thereof.
